Next to the apple the orange is by far the modt 

 important fruit in the United States, although it can 

 be grown only in special localities. It is to the Southern 

 sections of the country what the apple is to the JSTorthern 

 sections. It is a good shipping fruit, even better than 

 the apple, and its beautiful color and delicious flavor 

 make it a close rival. Orange growers are generally 

 very enthusiastic in their work, and well they should 

 be, for the beautiful tree with its bright green leaves 

 and wonderfully fragrant white flowers, followed by its 

 golden fruit, makes it an object for admiration, and 

 when the work is carried on in a systematic, business- 

 like way, except when injured by frost, orange growing 

 is profitable. 



While easily grown, the trees must have constant 

 care to keep them growing vigorously, and to protect 

 them from insect pests, and in some sections to protect 

 them from frosts.
